7'0 all whom. it may concern:

lie it. known that. 1, WILLIAM PETERS, a citizen of the linited States, residing at Peoria, in the. county of Peoria and State of Illinois, have invented certain new and useful Improvements in Elevating Apparatus; and I do hereby declare that thefollowing is a full, clear, and exact, description ol the invention, which will enable others skilled in the art. to which-it appertains to make and use the. same.

This invention has reference to certain new and useful improvements in elevating a 'tparatus and relates particularly to a conveying mechanism with which it is adapted to connect a dragfor receiving from a wagon or other suitable device material to be discharged into the lower end of the elevating means and elevated to a bin or other suitable receiving means.

One of the objects which I have in view is the supporting of the elevating means on a wheeled frame, and provided means at. the inward end of said wheeled frame and in connecti on with said elevating means whereby the receiving, end of the elevating means may be projected from and toward the end of the wheeled frame for the purpose of adjusting the. position of the receiving end ot' said elevating means.

A further object of the pre ent invention is combining an elevating means with a portable support and priwidingigeans at one end of said support and in conneetion with said elevating means ior adjusting the position of the receiving end thereof; and also in the provision of means having a folding connection with the pposito end of said support for elevating the disi charge end of said elevatmg means.

means adjustablv connected at its receiving end with a portable support; folding means at the opposite end of said support for raising and lowering the discharge end oi the elevating means; a receiving drag for conveying material into the receiving end of the elevating means, and in the provision ot a rest for the inner end of said drag adjustably connected with the receiving end of the elevating means.

A further object of the invention is an elevating means, a drag tor reeeivi ig and conveying material to the receiving end of the elevating menus, driving conneetions between the receiving end of the elevating means and inner end of the conveying means of the drag, said driving wuneetions adapted to have an interehangealile 'tillll't'CtiOll with the opposite sides of the elevating means and conveying means of the drag and" aim being such as to adapt the drag to have a horizontal swinging connection witlrsaid elevating'means.

For a further and full description of the invention herein and th. merits thereof. and-also to acquire a knowledge of the details of construction (ii-the means for effecting the result, reference is had to the following description an i drawings hereto attached.

While the essential and clniracterisl ic features oi the invention are susceptible. oi nnulitieation, still the preferred embodiment. of the invention is illustrated in the accompanying drawings, in which Figure 1 is a-greatly reduced side elevation of the portable support, the elevating means attached thereto and partly broken away, also showing the receiving drag in connection with the receiving end of the elevating means, but omitting the driving coinim-tions between the elevating meansnnd the drag; Fig. is an enlarged side elevation oi the lower and receiving end I of the elevating means-and showing the inner end of the drag supported in connection therewith; also the gearing between said ele ating means and drag; Fig. 3 is a view somewhat similar to Fig. 2, except that it. is a longitudinal and vertical section through the said parts; Fig. 4 is a top plan view of the lower or receiving end of the elevatingmeans; Fig. 5 is an enlarged vertical cross sect ion of the lower or rece. ving end 0f the elevating means, the inner end of the drag and the driving connections between the elevating means and the. drag; Fig. 5* is a detail showing a face vicwsn' certain parts seen in Fig. 5; Fig. 5 is a detail showing a face view of apart seen in Fi Fig. 6 is an enlarged detail in plan of the mechanism carried on the portable support to effect. the raising and lowering of the discharge end of the elevating means; Fig. 7 is a vertical sectional detail of the parts shown in Fig. (i; Fig. 8 is a detail elevation broken away and partly'in section showing an end view of one of the axles of the portable support and the means for assisting in elevating or raising the discharge end of the elevating means and bracing the same when raised; Fig. 9 is an enlarged detail in plan of one end of the drag; and Fig. 10 is a vertical cross section through that end of the Fig. I] is an enlargpd view of the lower right hand end of Fig. l.

7 Like numerals of reference indicate corresponding parts throughout the. figures.

In the drawings, referring particularly to the portable support, 1 and 2 denote front and rear axles carrying ground-wheels 3 and 4 upon the opposite ends thereof. The axle 1 has pivotally connected therewith by some suitable-means the cross-head 5 and connected with the said cross-head 5 and the axle 1 are the longitudinal and parallel frame-parts or stringers suitably spaced (i apart. There are also provided brackets '7 for rigidly conneetingth'e frame-parts 6 to the cross-head 5 and brackets 8 for rigidly connecting the fraiuepari. ti to the axle I. I have specified that the cross head 5 has a. pivotal connection with the axle I, this is to adapt the easy turning of the portable support when it. is being conveyed from place to place, although this connection Portable supports for this pur; pose are not entirely new'and the arrangement such as I have described has been shown as well as used.

5, and similar to Fi 5: 0

To the frames 6 and preferably at points above the axle 2 I have shown pivotally connected at 9 the lower ends of the uprights or sppports 10 which at their upper connected therewithqthrough suitablev clamping devices15.

At a suitable pohlt on the ira'mes 6 in advance of the axle 2 are secured bracketsl6 in which is journaled and extends transversely across the portable support formed by the frames 6, a shaft or spindle 17 On one end of this shaft or spindle see Figs. 1, 6 and 7 is carriecla worm-wheel or pinion 18 which is in mesh with a worm 19 carried by a short shaft or spindle Zlljournaled in bearings 21 attached to or forming a part of onoof the brackets 16, and the outer end of the said shaft'or spin; dlc 20 is squared as at 22 to adapt the connection there; with of a crank or handle 23. To facilitate in operating the shaft or spindle 20 for imparting motion to the shaft or spindle 17 through the worm-wheel 18 and worse 19 in mesh therewith, on theshaft. or spindle 17 and preferably adjacent tov the frames 6 I have provided the drums 24 with which may be suitably connected the cables 25 which extend up and over the sheave-wheels 11 supported by the uprights l0 and the ends of the said cables are sui ably connected with the elevating means in a manner to be described. While the drawings disclose only one side of the portable support it is to be understood that the same is in duplicate, with the exception that I prefer to provide only one bracket 16 such as shown in Fig. l and the gearing in connection therewith The shaft 17 carries a pair of the drums 24- and it is understood of course that the uprights or supports 10 and their connections with c the frames 6 are in duplicate.

.worm-whcols 30 on a transverse shaft or spindle 31 iournaled in the brnclqots 26. 'lhebracket 26 attached to the opposite frames 6, which is not shown is preferably without the bearings 27 as it is not necessary or desirable to duplicate the gearing shown in connection therewith uni-liar side of the support. The outer end of the haft or spindle 28, while not here shown, is squared somewhat similar to that shown at 22 on the shaft 2 to adapt the connection ihcrcwith of a crank or handle 32 to facilitate in operating the shaft 3] to the Worm and worm-wheel described and for purposes to be hereinafter more fully explained. On the shaft or spindle fit is carried, proh-rably the flange pinions 33, of which there is a pair, although not showrn serving, a purpose to be more fully explained.

The elevating means or conveyor to which reference has been made consists of the longitudinal and parallel spurnd side frames 34 connected by the bottom 35 oxtcndii'ic, approximately the length thereof and said other and longitudinally with the side-frames 34 is shown the supplemental side iramcs38 to which is sol l secured to the axle 2 and a a suitablc poiiit on the, uprights or supports lil the reaches or brace-rods are senses bottom has the sheet metal covering 36 and extending along-and above the bottom and adjacent to the side l'ramcs 34 are the-longitudinal cleats 37. Spaced a short distance below, extending parallel with each cured the cleats 39; the latter projecting ,a short distance inwardly toward each other and extending longitudinally with and approximately of the length of the supplemental side frames 38. The sidodrames shown. Y

Pivotally attached to have a folding connection with the'devices above-described, whichiorms the lower section of the elevating means or'conveyer is shown an, upper section consisting of the side-frames 34 and h or supplemental frames 38 adapted to .be connested with-and braced by straps similar to those shown at 40, although none are shown in connection with the folding section. And while not shown, the folding section has a bottom similar to that shown at 36 and provided with cleats similar to that shown at 39. The upper and folding section just described is pivotally connected at 41 with the lower section and like devices of this character when transporting the machine irorn place to place or storing the same the upper and folding section may be folded back and upon the lower section 1 p The lowerpnd forward; end of the elevating means just describcd serves as 'the receiving end thereof and is closed by the shield or plate 42. Travel t through the two sections of the elevating means and serving as a conveycizj or carrier adapted to receive and convey mathrial from the lower receiving end to the upper discharge end thereof is shown the pairof endless chains or link-belts 43 which are adapted to travel over and along the cleats 37 attached to the bottom of the sections formed by the side-frames 34 and 34. These 7 chains or link-belts are driven by the driving-sprockets 44 with which they engage carried by the transverse] disposed driving-shaft 45 located in the lower and receiv ing end of elevating means. The said chains or link-loclts-have the discharge end of the elevating means travel over sprocket-wheels, not shown, similar tothose'indicated as 44 and carried by the transversely disposed shalt 46. Connecting the chains or link-belts 43 at desired intervals are theflights 47, substantially as shown in the figures which, as they .travel up wardly through and between the frames 34-and 34 move along and over the bottom connecting the same and in their return movement the said flights travel along and above the cleats 39 sccurcd'to the supplemental framcs 3S and 38", all of which it is believed is understood.

The shaft or spindle indicated as 31 above referred to is adapt 'd to be canicd transvcrscly through the lower section of the elevating moans. That is to say, thi-v frame constituting the elevating means in which the carrier or conveyor consisting of the endless chain or bolting is operated, is 'ol' loss width than the width oi the portablev support between the side frames (5 and the lower end of the elevating means is so positioned that the shell 31 is carried transversely through th same in the space between the side and supplemental Y 7 5 I 34 and 38 are connected and-braced by the connecting .straps indicated as 40 and arranged substantially as ira mos 34 and 3S and to prevent sagging of the said shaft and also play hotwoon thc'lowor and uppor cdgos of tho iramos 3-1 and 38 I insert tho iillingplatos 4T and 48 as shown.

I have provided in connection with'the lower and receiving end of the elevating ineans side supports orattachments to serve as a receiving hopper in connection with said elevating means. This consists of the sideiranies 74 of suitable length secured to the forward end of the frames 34 by the straps 35 and adjustably connected with'the fra1ncs 74 are the hopper sides or plates '76. The adjustable connection between the hopper sides of the plate 76 and the frame 74 consists in slotting the plates 76 at 77 and securing the same by means of the toms.

I have pro \'ided in connection with the sides 51 of the drag interchangeable parts consisting of a shield and a feeding-spout having a fold-able section. It is adapted in connecting the drag with the elevating means to attach the same in a manner to' be described therewith so that the drag may have horizontal movement. This provision is made so that as a wagon is driven up to the elevating means and its front end elevated to allow the material therein to be dumped into the drag, that the drag may be swung out of the way and then into position again. When it has assumed its position to receive" the material from the wagon, substantially as seen in Fig. 1 the spout relerred to as being attached to the drag is attached to that side of the drag to receive the material andthe shield referred to is attached to the opposite sidethereof to prevent the material from tailing over vthe opposite, side ofithe drag. The shield above redove-tail connection with either-one of the sides 51, at

the cut out portions thereof which is also substantially seen in Figs. 9 and 10. The section 81 is an extension of the part 80 and pivoted thereto at 82, the same being yieldingly held in its relative positionwith the part 80 when unfolded by means of the springs 83 attached at their opposite ends to the sections 80'and 81 substan-' tially as seen in Figs. 9 and 10. With the above construction, it will be seen that the shield 79 and the chute or spout consisting of the sections 80 and 81 are inter changeable from one side of the drag to the other to adapt the unloadingoithe material from the wagon into the said drag l'romeither side.

'lhc drag is of less width than the sections forming the elevating mechanism carried by the portable support and when the inner end thereol rests on the frame 01 the drag is in a position substantially as seen in Figs. 1', 2, 3 and 5 and it is adapted, by means-to be described, to drive the carrier or conveyor of the drag from the driving shaft 45 which drives the carrier or conveyor ol' the elevating means. This driying n'icchanisin also includes a swivel connection to'adopt a horizontal swinging connection ot' the drag with thereceivihg end of the elevating means and is further adapted to l have an interchangeable connection with opposite sides oi the elevating means also the drag.

length to adapt the same to have falfixed connection with thesquared endsoi the'shaft 84. 'Intermeshing with the beveled gear 02 ,is a bevel gear 9f carried on the'lower end of a shaft 95 which passes up through and has bearing the elongated tubular bearing 88 of the bracket 87, thie'shaft hasan elongated squared extensipn indicated as 96 serving a purpose. to be described. \The driving shaft 57 of the conveying means in the drag is extended beyond the opposite ends thereof and has the squared ends 97, the said shaft being somewhat similar to, that shown as the driving-shaft 45 The ex tended ends of the shaft 57 passes through the disks or plates 98 attached to the sidefrarnes 51 of'the drag are provided, preferably, with the pair of outwardly. and inwardly projected lips or cars 9, between which? and the body of the platefis provi ed a suitablo'space for ap rpose to be described. v I l H V 100 denotes a bracket which is similar-to the bracket Sil -and the same is provided with the elongated tubnlari' bearingl'Ol and the short tubular bearing'102 prdirided with an outer-flange 103 havingoppositely"disposed slots 104 therein corresponding approximately, to the' depth of the lips 9}) formed on theplate is .dcsired to have the bracket 100 detacltiably and interchangeably connected with the plates 98 and to connect the same in working position thereon td'receive parts to be described, the slots 104 of the flange 103 of thebracket 100 are slipped over the lips 99 of the plate 98 and then turned into a working position as shown in the figurcswhich locks the bracket 100 in connection with the plate 98 and while allowing rotary motion in connection with the said plate the sarne is held in a substantially non-detachable relation until the bracket 100 has been turned so that the slots 104 of the flange 103 co-incide with the lips 99 to permit the same to be do tached therefrom. i

I denotes a beveled gear wheel having a hub portion which has a bearing in the short tubular bearing 102 of thebraeket 100, which is squared internally ap- 1 proximately its length to adapt the same to have a fixed gated sleeve lil7 loosely carried by the bracket 100, in

the manner seen in Fig 5 which has a squared opening extending through the same to correspond to the squared portion of the shaft 95.

With the provision of the brackets 87 and W0 together with the'plates attached to the elevating means and die drag and also the gearing specified it will be seen that the same may have an interchangeable connection with one side or the other of the elevating means and the drag and that suitable power connections may be made with the squared extensions 84 of the drive-shaft 45, as by means of a'tuinbling-shait, not shown. lrom a horse-power or by other suitable power conn ctions. The further advantage of the driving ion nee! ions bet ween the shaft of the elevating means and the shaft 57 of the drag is, that the drag may have a swingable connection with the elevating means. That is lo say, the drag may have a horizontal swinging movement in connection with the shaft 95 which serves as a pivotal point about which the drag may be swung, all of w eh it is. believed will be understood. And further, lhe drag may be easily attached to or disconneel ed from the elevating means and the power connec-' It is to be noted that in elevating or raising the discharge end of the elevating means through the operal ion of the drum shaft 37 for wrapping the cable 25 tli r'eon, that as the cieval iug means is raised the uprights l0 are also raised, and when the shaft 17 is operated to unwind. th cables 25 therefrom as the elevating means is lowered the uprights also automatically lower, the

speed at which they drop being controlled by the calit) les which pass over the sheave wheels as shown.
